Title: Measuring instrument for precursory vibration of earthquake
Inventor: FUJIWARA MINORU
IPC: G01V1/00
Filed: 1992-10-27
Abstract: PURPOSE:To provide earthquake prediction by measuring and computer- processing the high and low frequency band vibrations of the precursory phenomenon of earthquakes. CONSTITUTION:A water-immersed vibration sensor 1 is installed in a pipe reaching the bedrock of a fault plane where an earthquake is supposed to occur, to detect acoustic emission(AE) from a focal region and low frequency vibration, etc., that takes place just before the earthquake as electric signals. The electric signals are amplified by means of a preamplifier 3 and then separated using a high-pass filter 4 and a low-pass filter 5 into vibration levels of each band, and transmitted through an amplifier 6 and an A/D converter 7 and those data are transferred to an output controller 8 and a computer 9, which then makes calculations for earthquake prediction. A temperature sensor 2 performs remote measurement of the temperature rise of soil, etc., due to ultrasonic heating to supplement information about inland earthquakes.

Title: Device for putting on discharge lamp
Inventor: TANAKA KUNIO
IPC: H05B41/42
Filed: 1989-12-20
Abstract: PURPOSE:To enable dimming operation in a shortest time by reducing the time for preheating at a start-up initializing frequency when the ambient temperature is high while increasing it when low. CONSTITUTION:In the case of initializing the start-up for preheating, starting the discharge, maintaining the lighting operation and performing dimming by changing the frequency of high frequency inverter 2, the time for attaining the frequency is determined by the time constants of circuit elements of an integrated circuit ICI and comparators CP1, CP2. When a thermistor TH1 is connected to the plus side of the comparator CP1, the time constants are in creased with the result of long preheating time because the resistance of the thermistor TH1 is increased at the time of low temperature. The preheating time and the time till dimming operation are decreased because the time constants are reduced on the contrary at the time of high temperature.
